Specification of Letters Patent;

Patented Apr. 22, 1913. 1

To all whom it may concern: 1

Be it known that I, GLENN Ga: ,RIEIINE-j VAULT, a citizen of the i United :States, 1 re: siding at Saginaw, in the county of Saginaw and State ofMichigan, have invented certain new and useful Improvements ill'l Broken Rolls; and I do hereby [declare thefollowingto be a full, clear, and exact description of the invention, such asvwill enable others skilled in the artto which it appertains to make and use the same. This invention :relates to: feed irolls such as are commonly used irrmachines for resawing boards, and the improvement pertains more particularly to 1 the 1 construction of such a feed rollimade up ofa number of short sections :placed fiend to s end, comprise ing what is commonly known as a broken roll, all of the sections beingrotated 1posi tively in the same ;direction,; but each i sec-v tion being capable of bodilymovement side-v wise with relation tothe remaining sections without: affecting either, the 1 driving; power or the peripheral speed of rotation ofmthe sections.

In various arts there :are many uses for sectionalwrolls of ithis 1 nature, but since brokenrolls are especially well adapted for use in band resawing machines, a my inven:

0 tion willbe describedfor convenience in this specification as being used 1011 resawing mam chines. 1 v v To illustrate somevof the: general conditions of use of the device, I will cite for ex: ample, the resawing; of certain: kinds of lumberused in the manufacture of ibox shooks. i l

It is customary for boxmanufacturers to; dovetail together odd pieces of scrap lumber to form a slab of considerable width; to surface oneside of the slab and then to pass it through a resawing machinathe surfaced side of the slab lying against the fixed rolls of the machine in its passage through the saw. The yielding rolls, if made, in a single piece, as is nowcommonywill ride'usually at only one place on the slab, where the builtup piece happensto :be thickest, allowing the other portions of the slab tospring away from the fixed r011 producing a resawed board of uneventhiclmess and often spoiling it. Therefore, it becomes necessaryto provide a yieldingroll that will not only positively feed the slab forward, but will: by 5 reason of its yieldingly-mounted independent power-driven sections press against the slab at, a number of places: so as to prevent the slab from springing away from the fixed rolls and therebyinsure an even cut. It is 9' desirable inathis class of worklthat the rolls 160 1 be of relativelysmall diameter andyet be; capable of a considerable yielding move ment toward and from the line of cut, the;

rolls beingusually made about four inches: in diameter, each section 1 being capable 1 of 1 anindependent lateral movement of about: five-eighths of an inch toward and from the! line of cut. My invention provides mechanism for accomplishing these results.

j The invention also comprises certain com 701 structions and combinations and the e UlVik, lents thereof, which will: be described in the specification andpointed out in the claims.

In thedrawings, Figure 1 is a perspectlve view showing my improved broken roll I mounted in :the roll frame of a resawing: machine; Fig. 2 is a top plan view of a roll section; with: its supporting yoke attached,

the yielding movement of the roll and: yoke being indicated by; dotted lines; Fig. Slis 1801 a vertical section through one of the roll sections, with the yoke turned out of its normal position for better illustration; Fig;

Fig.12; Fig. 14 is a bottom plan, view ofi the :parts shownvin Fig. 12; Fig. 15 is a top 1 plan view of the modified form shown in Fig. 9; Fig. 16 is a vertical section taken on the liner y ofiFig, 15; Fig. 17 is a horizontal section on the lineefie of Fig; 16; Fig. 18 isa bott0m view of the parts shown mFig. 16.

Referring toFig. 1, the roll sections are, shown arranged vertically, each section being adapted for indepen ent movement, toward andfrom the line of cut by contact with the slab asit passes throughthema- 1101 1 is the outer revolving shell of the roll section, and 2 is the spring-pressed yoke.

Referring to Figs. 2, 3 and 5; 3 is a shaft revolubly mounted in bearings carried by the roll frame. of the machine, the shaft being driven by any suitable means, as by a train of gears located at the top of the roll,

framein the usual manner, as, shown in Fig. 1... When the shaft is. to be used in vertical position, as shown inFigs. 1 and 5,1 provide a removable sleeve or. foot-step collar bearingt to sustain part of the Weight. of the shaft and the parts supported by it. On the shaft 3 are pinions 5,. one for each roll section. 7

As shown in Fig. 3, the cylindrical shell 1 surrounds pinion 5 and an internal gear 6 carried .by the shell is in mesh wit-h the pinion, so that the revolving of thepinion drives the shell.

To support the shell in proper drive relation with the pinion and to permit the shell to move toward and from the line of out without interfering with the proper meshmg, of the ,gear and pinion, I provide a journal upon which the shell revolves, the

journal preferably comprising the following.

devices.

Two members, which I term the upper journal member 7land the lower journal member 8 are swiveled eccentrically 'upon the shaft and are received within'the shell 1, the peripheries of these journal members serving as bearings, upon which the, shell 1 turns when pinion 5 rotates.

The upper and lower journal members 7 and 8 are preferably held together by a yoke pin 9 carried by the yoke 2, the yoke being arranged in practice asshownin Fig. .2, .GX- tending, approximately at right angles. to the diametrical line that connects the center of shaft 3 with the center of. pin 9, so that movement of the roll section towardfand from the .line of cut will produce longitudinal movement of the yoke 2 and vice versa.

To receive pinion 5, I provide members 7 and8 "with recesses '10 and 11 respectively, and'simil'arly, to receive the teeth ofgear 6 I providean annular recess 12 around the lower periphery of member .7 and a similar annular recess 13 around the upper periphery of member 8, so that the members 7 and 8, when placed together as shown in Fig. 3, will provide a cavity, within. which pinion 5, is received, and an annular groove within which the teeth of internal gear 6 are received. To reduce the. wear between the inner face ofshell 1 andthe bearing surfaces of the journal members 7 and 8, I may in-.

sert an antifriction lining, as a layer of fiber'la. To keep outdirt, the. upper and lower extremities of members 7 and 8 may be providedrespectively with "flanges15 and 16"tha't 'project overthe joint formed bythe rubbing. surfaces, as shown in Fig.

- Lubrication maybeprovided-by recessing the outer faces of the journal members to form" pockets. 17 with inwardly-pro ect1ngfia'nges lh A pad 19. of:felt or pther abs sorbent material is inserted in theaabottom of thepocket'and is. held in place by the flanges 18. Oil holes 20 conduct lubricant from the pad to the surface of thejjourn a'l- In practice I prefer to form the shaft 3 and pinion 5 in a single'piece,in which case it is not convenient to assemble the middle sections by sliding the members 7 and 8 over the shaft lengthwise,-for' the reason that the pinion 5 is larger than the holes 21through' which shaft 3 passes and by which thejour nal members are swiveled on theshaft. To overcome this difiiculty, large bushings ordi narily have to be provided,atqconsiderable expense. I, therefore, prefer to provide for members 7 and 8 of these middle sections a modified construction substantially; as illustrated in Figs. 7, 8- and 11, inwhich 22 is a block of metal equal in' width tothe diameter of hole 21, theblock being removably inserted in the journal member and held in place by guides 23 that slide into grooves formed in the journal member;

When blocks 22are removed, journal mem;

bers 7 and 8 may beslipped sidewise over the shaft and pinion, and blocks 22 arethen put in place, after which the journal mem: bers are brought together and enteredin the shelll, as indicated inFig. 3. r

The outer journal 'member 'of the upper. pinion on shaft 3, and-of the lower pinion. also if desired, can be assembled by slipping.

it over the end of the shaft; and, therefore,-it need not be providedwiththe removable block 22 above described, but may be made in one piece as shownin Figs. 15 to 18." I

The yoke 2'is provided with a threaded stem 24 'whichpasses slidingly throughan opening in a figred member, as post 25, the limit of sliding movement being determinedby the adjustment of nuts 26"on one sidejfof. the post and by a shoulder 27 'formedfon the,

stem 2a and located 'onthe otherside ofthe post. A. compression spring28 is inserted between the. post and the yoke to-keepv the yoke and roll. section pressed normally out: ward. v 1 I 3 While I have shown and described certain specific details of construction, as v;for--instance, details ofrthe .shell .l land ;jour-nal.l members 7 and 8, it will be understood that thesedevices are susceptible of various mod- 1 ifications without departing fromv the spirit of my invention- Having described my invention, what I claim and desire to secure by Letters Patent,

,is: 7 i 1. A roll section comprising in combinationwith a revoluble shaft, a,pinion fixed to said shaft, an internalgear in mesh with said pinion, a shell carried by said gear, and a journal member, adapted to revolubly support; said shell, said journal member; com prising upper and lower cylindrical sections formed with recesses at their, adjacent ends to receive respectively the pinion, and, in:

ternal gear, each of saidmembers provided" with an opening through which said shaft passes, a removable block equalin width to said shaft opening; andmeans adapted to allow oscillation of the journalmemberu 2. A roll-section comprising, incombination with arevolublei shaft, a;pinion:fixed to said shaft, an internal gear in mesh with saidpinion, a shell carried by said gear, and a journal member adapted :to revolubly sup port: said :shell,% said journal member comprising upper and lower cylindrical sections formed with recesses at :their adjacent ends to receive respctivelythe pinion and internal gear, each of said members provided: with an openin throughi'which said shaft passes, and aisi e-opening, having its walls, formedwith grooves therein, a removable block for each shaft openinggguides 'onsaid block slidably received in 1 said grooves, and 1 a spring-pressed yoke pivotally connected to; said cylindrical sections.
